I needed a wireless remote control for my camera but they are kinda expensive. The official Canon remote costs about half a month of minimum wage where I live. So I went for a less expensive solution, found this cheap wireless doorbell and hacked it to work as a remote trigger:
I've been studying the security aspects of network protocols and decided to take a look on the protocol used by a fun online game called "Among Us". If you don't know it, the game is very similar to the old board game "Clue". Do you remember "The assassin was colonel Mustard, with the candlestick, in the library"?
This is a Python script I made to generate an animated version of the cover image of the classic album "Unknown Pleasures" by Joy Division
This GIF is lousy. Check the video!
In the previous parts of this work I've gained access to the camera operating system and found the main program, "IPC", which controls everything related to video transmission. This part will document my attempts to reverse engineer this software.
In Part 1 of this analysis I started gathering information about this camera, and in Part 2 I found a way to gain root access to its operating system. This part will document the exploration I did using this access
So, the first thing I want to know was what processor this hardware is based on. This can be done by cat /proc/cpuinfo
In Part 1 we found out that the camera runs over Linux, but there are no SSH port open for a remote shell connection. So I'll try something more hardcore: Let's disassemble the camera
A few days ago I had to replace the old IP camera I use to watch over my dogs and cats, and found out that IP cam technology changed a lot since I bought that old camera. IP cameras are now low-price and ubiquitous. I bought one of those generic models and installed it at my home, expecting to use the same software and network configuration I used before. However, these new cameras do not work the same way. They didn't gave me the same control I had over the old model.
A bibliteca Mallandro permite reproduzir no Arduino algumas das clássicas falas deste que é um dos maiores artistas brasileiros vivos: Serginho Mallandro. Esta biblioteca foi desenvolvida para ser usada no projeto "Campainha Mallandrinha", que anuncia aos frequentadores do SJC Hacker Clube a chegada de visitantes.
Para utilizá-la, basta fazer o download do arquivo abaixo, que está em formato workspace do MariaMole, mas é fácilmente adaptável ao IDE do Arduino: Basta renomear o arquivo example.cpp para example.ino.
Intel Edison is a nice Internet of Things device. On a module the size of a SD card, you get a dual-core computer with WiFi and Blutooth. You can also get an Arduino compatible development board, to attach Edison and use Arduino shields on it
Hello, Arduino programmers!
Thanks a lot for the comments, suggestions, complaints and bug reports you've sent me about MariaMole. Thanks to your messages the version 0.4 is already available and very stable. For many people, MariaMole is already the first option when they start a new Arduino project. Nothing could make me happier. I started it trying to create the IDE I wanted to use, and now I see a lot of positive comments from people all around the world, telling me they don't want to go back to the original Arduino anymore. That's really great!
